Six football fans arrested after an offensive banner was unfurled at Millwall have all been released on bail.

A sign directed at Bolton striker Marvin
Sordell, who was racially abused by one of the club's fans last month, was
unveiled at The Den during the Lions' 2-1 win against Derby County on Saturday.

The banner, which said "Sordell is a
c***", related to complaints made by Sordell after he was abused by fans
while warming up for a match on October 6, leading to a 13-year-old boy being
banned from Millwall's ground.

A Metropolitan Police spokesman said six
men were arrested on suspicion of public order offences and have been bailed
until early December.

The banner on display was swiftly removed
by Millwall staff.

The club has so far refused to comment on
the issue, and assistant manager Joe Gallen - standing in for Lions manager
Kenny Jackett, who missed the game with flu - also opted not to discuss the
matter.

Sordell took to Twitter after the Millwall
match last month to claim that he and team-mates Lee Chung-young, Darren
Pratley and Benik Afobe were subjected to racist taunts.

That sparked an investigation led by both
clubs and last week Millwall confirmed the boy in question admitted to abusing
Sordell and subsequently issued a written apology which the player accepted.

Given his age, Millwall have not imposed a
life ban on the youngster and offered him a place on a "Millwall for
All" educational programme "in the hope that we can change his
outlook on equality, racism and life in general".
